A man has been arrested in connection with two gun and grenade attacks which left a man dead.

David Short, 46, was hit by several bullets and also suffered blast injuries in the first attack in Clayton, Manchester, on Friday morning – weeks after his son Mark, a 23-year-old amateur boxer, was shot dead when a gunman opened fire in a pub in the city.

Greater Manchester Police said a 37-year-old man was arrested on Saturday on suspicion of murder in connection with Friday's attack in Clayton, and a second gun and grenade attack which took place minutes later in Droylsden.

Officers are searching for Dale Cregan, 29, for questioning over the two incidents. He is also wanted in connection with the murder of Mark Short. Armed police have patrolled the Clayton and Droylsden areas since the attacks.

David Short's body was found when police responded to reports of gunfire. A post mortem examination concluded that he died from multiple gunshot wounds and blast injury. After his son was murdered, he and his family released a statement saying Mark had been "taken away from us by cowards".
